analogous apparatus, and the object is to provide mechanism that is simple in con-l struction -and adaptable for use with the ordinary freezer' or other structures, thus making it peculiarly applicable to domestic purposes. f

InV the accompanying drawings, two embodiments of the invention are shown, wherein z* Figure 1 is a plan View of an ice cream freezer complete,

Figure 2 is a side elevation of the same,

Figure 3 is a plan view ,on an enlarged scale with parts removed, illustrating one form of the gear mechanism,

Figure 4 is a sectional view through the structure illustrated in Figure 3,

Figure 5 is a plan view with parts removed and with parts broken away' of a differentv form of construction,

Figure 6 isy a vertical sectional view through the mechanism illustrated in Figure 5.

In the drawings, an ordinary ice cream freezer tub 7 is illustrated, which in Figures 2, 3 and 4 contains a rotatable can 8, in which is placed a fixed agitator 9. The

tub is provided on one side with a pair ot fixed hooks 10, and on the other side with a swinging latch 11. l

A support in the form 'of a bridge piece 13 is adaptedto be placed on the tub and has at one end a head 14 provided with sockets 15 to receive the hooks 10. Its other end is provided with an opening 16 to receive the latch 11, whereby the bridge piece is effectively mounted on the tub.

This bridge piece' has an integral upstanding casing 17 and a depending boss 18. In the latter is journaled a tubularshat 19 having at its upper end a, gear 20 that. is located in the casing 17, its lower end terminating in clutch teeth 2l adapted to interlock with corresponding teeth 22 formed on the cover 23 of the can. A cover 24,

located on the casing 17, constitutes a'sup# port for an electric motor, the housing of which is designated 25, and which motor may be of any desired character. ThisA motor has attached thereto a cord 26 provided with a suitable plug 27 which can be inserted in any well known electrical socket.

A controlling switch of any desired char-k` v acter is shown at 28. The top ofthe motor casing 25 is 'in the form of a handle 29. z

The shaft of the motor is shown lat 30, and is journaled in the top 31 as shown at 32. Y The lower end of this shaft is provided with a pinion 33 .that meshes with a gear wheel 34. This gear wheel carries a pinion 35 in mesh with another gear 36. The gear 36 has fixed thereto a pinion 37 in mesh with the gear wheel 20. It will thus be seen that" the motor will effect the rotation of thecan 8 through the t-rain of gearing housed within the casing 17.

The agitator 9 has a shaft 38 that extends into the hollow shaft 19 and terminates in an angular portion 39 'detachably received in the socket 40 of' a bracket 4l fixed -within the casing 17 The agitator is thus held against rotation.

In the embodiment illustrated in Figures 5 and 6 the can and agitator are rotated in opposite directions. ln this embodiment of the invention the tub is designated 42 and has detachably mounted thereon the bridge piece 43 carrying the housing 44, said housing having a top 45 supporting the motor, the casingof which is designated at 46. The motor shaft is designated 47 and terminates in a pinion 48 that is in mesh with a gear wheel 49. rlhis gear wheel has a pinion 50 meshing with a gear wheel 51 that carries a long pinion 52. The pinion 52 is in mesh with an idler 53 that operates a Gear 54 on the upper end of a shaft 55 that detachably interlocks with the agitator 56. Thel pinion 52 is also in direct mesh with a. gear 57 carried bythe upper end of a tubular shaft 58, clutched, as shown at 59, to the top 60 of the .can 61. With this construction, it will be evident that the can will be rotated in one direction and the agitator in an opposite direct-ion.

From the foregoing, itis thought that the construction, operation p and many advan.-
